* bpo-46836: Rename InterpreterFrame to _PyInterpreterFrame (GH-31583)Victor Stinner2022-02-251-26/+26
| | | | | Rename also struct _interpreter_frame to struct _PyInterpreterFrame. Reduce risk of name conflicts if a project includes pycore_frame.h.
* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-081-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | global objects. (gh-30928) We're no longer using _Py_IDENTIFIER() (or _Py_static_string()) in any core CPython code. It is still used in a number of non-builtin stdlib modules. The replacement is: PyUnicodeObject (not pointer) fields under _PyRuntimeState, statically initialized as part of _PyRuntime. A new _Py_GET_GLOBAL_IDENTIFIER() macro facilitates lookup of the fields (along with _Py_GET_GLOBAL_STRING() for non-identifier strings). https://bugs.python.org/issue46541#msg411799 explains the rationale for this change. The core of the change is in: * (new) Include/internal/pycore_global_strings.h - the declarations for the global strings, along with the macros * Include/internal/pycore_runtime_init.h - added the static initializers for the global strings * Include/internal/pycore_global_objects.h - where the struct in pycore_global_strings.h is hooked into _PyRuntimeState * Tools/scripts/generate_global_objects.py - added generation of the global string declarations and static initializers I've also added a --check flag to generate_global_objects.py (along with make check-global-objects) to check for unused global strings. That check is added to the PR CI config. The remainder of this change updates the core code to use _Py_GET_GLOBAL_IDENTIFIER() instead of _Py_IDENTIFIER() and the related _Py*Id functions (likewise for _Py_GET_GLOBAL_STRING() instead of _Py_static_string()). This includes adding a few functions where there wasn't already an alternative to _Py*Id(), replacing the _Py_Identifier * parameter with PyObject *. The following are not changed (yet): * stop using _Py_IDENTIFIER() in the stdlib modules * (maybe) get rid of _Py_IDENTIFIER(), etc. entirely -- this may not be doable as at least one package on PyPI using this (private) API * (maybe) intern the strings during runtime init https://bugs.python.org/issue46541
* bpo-43683: Streamline YIELD_VALUE and SEND (GH-30723)Mark Shannon2022-01-241-2/+4
| | | | | | | | * Split YIELD_VALUE into ASYNC_GEN_WRAP; YIELD_VALUE for async generators. * Split SEND into SEND; YIELD_VALUE. * Document new opcodes.
* bpo-46409: Make generators in bytecode (GH-30633)Mark Shannon2022-01-201-21/+36
| | | | | | | | | | | | * Add RETURN_GENERATOR and JUMP_NO_INTERRUPT opcodes. * Trim frame and generator by word each. * Minor refactor of frame.c * Update test.test_sys to account for smaller frames. * Treat generator functions as normal functions when evaluating and specializing.
* bpo-45711: Remove type and traceback from exc_info (GH-30122)Irit Katriel2021-12-171-6/+0
| | | | | | | | * Do not PUSH/POP traceback or type to the stack as part of exc_info * Remove exc_traceback and exc_type from _PyErr_StackItem * Add to what's new, because this change breaks things like Cython
* bpo-46039: Split yield from in two (GH-30035)Mark Shannon2021-12-151-7/+11
| | | | | | * Split YIELD_FROM opcode into SEND and JUMP_ABSOLUTE. * Remove YIELD_FROM opcode.
* bpo-46008: Make runtime-global object/type lifecycle functions and state ↵Eric Snow2021-12-091-0/+1
| | | | | | | | | | | | consistent. (gh-29998) This change is strictly renames and moving code around. It helps in the following ways: * ensures type-related init functions focus strictly on one of the three aspects (state, objects, types) * passes in PyInterpreterState * to all those functions, simplifying work on moving types/objects/state to the interpreter * consistent naming conventions help make what's going on more clear * keeping API related to a type in the corresponding header file makes it more obvious where to look for it https://bugs.python.org/issue46008
* bpo-46009: Do not exhaust generator when send() method raises (GH-29986)Mark Shannon2021-12-081-0/+13

* bpo-45963: Make space for the InterpreterFrame of a generator in that ↵Mark Shannon2021-12-061-84/+99
| | | | | | | generator. (GH-29891) * Make generator, coroutine and async gen structs all the same size. * Store interpreter frame in generator (and coroutine). Reduces the number of allocations neeeded for a generator from two to one.
* bpo-45786: Allocate space for frame in frame object. (GH-29729)Mark Shannon2021-11-291-7/+15

* bpo-44525: Copy free variables in bytecode to allow calls to inner functions ↵Mark Shannon2021-11-231-11/+10
| | | | | | | | | | | to be specialized (GH-29595) * Make internal APIs that take PyFrameConstructor take a PyFunctionObject instead. * Add reference to function to frame, borrow references to builtins and globals. * Add COPY_FREE_VARS instruction to allow specialization of calls to inner functions.
* bpo-45813: Make sure that frame->generator is NULLed when generator is ↵Mark Shannon2021-11-221-0/+1
| | | | deallocated. (GH-29700)
* bpo-45637: Store the frame pointer in the cframe (GH-29267)Mark Shannon2021-10-281-5/+5
| | | * Rename 'frame' to 'current_frame'
* bpo-45522: Allow to disable freelists on build time (GH-29056)Christian Heimes2021-10-211-5/+21
| | | | | | | | Freelists for object structs can now be disabled. A new ``configure`` option ``--without-freelists`` can be used to disable all freelists except empty tuple singleton. Internal Py*_MAXFREELIST macros can now be defined as 0 without causing compiler warnings and segfaults. Signed-off-by: Christian Heimes <christian@python.org>
* bpo-45439: Move _PyObject_CallNoArgs() to pycore_call.h (GH-28895)Victor Stinner2021-10-121-4/+5
| | | | | | | * Move _PyObject_CallNoArgs() to pycore_call.h (internal C API). * _ssl, _sqlite and _testcapi extensions now call the public PyObject_CallNoArgs() function, rather than _PyObject_CallNoArgs(). * _lsprof extension is now built with Py_BUILD_CORE_MODULE macro defined to get access to internal _PyObject_CallNoArgs().
* bpo-45439: Rename _PyObject_CallNoArg() to _PyObject_CallNoArgs() (GH-28891)Victor Stinner2021-10-111-1/+1
| | | | | Fix typo in the private _PyObject_CallNoArg() function name: rename it to _PyObject_CallNoArgs() to be consistent with the public function PyObject_CallNoArgs().
* bpo-45355: Use sizeof(_Py_CODEUNIT) instead of literal 2 for the size of the ↵Serhiy Storchaka2021-10-031-1/+1
| | | | code unit (GH-28711)
* Clean up initialization __class_getitem__ with Py_GenericAlias. (GH-28450)Serhiy Storchaka2021-09-191-1/+1
| | | | | The cast to PyCFunction is redundant. Overuse of redundant casts can hide actual bugs.
* bpo-44990: Change layout of evaluation frames. "Layout B" (GH-27933)Mark Shannon2021-08-251-7/+3
| | | Places the locals between the specials and stack. This is the more "natural" layout for a C struct, makes the code simpler and gives a slight speedup (~1%)
* bpo-44590: Lazily allocate frame objects (GH-27077)Mark Shannon2021-07-261-70/+195
| | | | | | | | | | | | | | * Convert "specials" array to InterpreterFrame struct, adding f_lasti, f_state and other non-debug FrameObject fields to it. * Refactor, calls pushing the call to the interpreter upward toward _PyEval_Vector. * Compute f_back when on thread stack, only filling in value when frame object outlives stack invocation. * Move ownership of InterpreterFrame in generator from frame object to generator object. * Do not create frame objects for Python calls. * Do not create frame objects for generators.
* bpo-42747: Remove Py_TPFLAGS_HAVE_AM_SEND and make ↵Petr Viktorin2021-07-231-6/+3
| | | | | | | | | | | | Py_TPFLAGS_HAVE_VERSION_TAG no-op (GH-27260) * Remove code that checks Py_TPFLAGS_HAVE_VERSION_TAG The field is always present in the type struct, as explained in the added comment. * Remove Py_TPFLAGS_HAVE_AM_SEND The flag is not needed, and since it was added in 3.10 it can be removed now.
* bpo-44530: Add co_qualname field to PyCodeObject (GH-26941)Gabriele N. Tornetta2021-07-071-1/+1

* bpo-44032: Move data stack to thread from FrameObject. (GH-26076)Mark Shannon2021-05-211-6/+6
| | | | | | | | | | | | | | | | * Remove 'zombie' frames. We won't need them once we are allocating fixed-size frames. * Add co_nlocalplus field to code object to avoid recomputing size of locals + frees + cells. * Move locals, cells and freevars out of frame object into separate memory buffer. * Use per-threadstate allocated memory chunks for local variables. * Move globals and builtins from frame object to per-thread stack. * Move (slow) locals frame object to per-thread stack. * Move internal frame functions to internal header.
* bpo-42800: Rename AUDIT_READ to PY_AUDIT_READ (GH-25736)Steve Dower2021-04-301-6/+6
|
* bpo-42800: add audit hooks for f_code and tb_frame (GH-24182)Ryan Hileman2021-04-291-6/+6
| | | | | | | | | | Accessing the following attributes will now fire PEP 578 style audit hooks as ("object.__getattr__", obj, name): * PyTracebackObject: tb_frame * PyFrameObject: f_code * PyGenObject: gi_code, gi_frame * PyCoroObject: cr_code, cr_frame * PyAsyncGenObject: ag_code, ag_frame Add an AUDIT_READ attribute flag aliased to READ_RESTRICTED. Update obsolete flag documentation.
* bpo-43683: Handle generator entry in bytecode (GH-25138)Mark Shannon2021-04-061-21/+6
| | | | | | * Handle check for sending None to starting generator and coroutine into bytecode. * Document new bytecode and make it fail gracefully if mis-compiled.
* bpo-27129: Use instruction offsets, not byte offsets, in bytecode and ↵Mark Shannon2021-04-011-2/+2
| | | | | | | internally. (GH-25069) * Use instruction offset, rather than bytecode offset. Streamlines interpreter dispatch a bit, and removes most EXTENDED_ARGs for jumps. * Change some uses of PyCode_Addr2Line to PyFrame_GetLineNumber
* bpo-43268: Pass interp rather than tstate to internal functions (GH-24580)Victor Stinner2021-02-191-5/+5
| | | | | | | | | | | | | | | Pass the current interpreter (interp) rather than the current Python thread state (tstate) to internal functions which only use the interpreter. Modified functions: * _PyXXX_Fini() and _PyXXX_ClearFreeList() functions * _PyEval_SignalAsyncExc(), make_pending_calls() * _PySys_GetObject(), sys_set_object(), sys_set_object_id(), sys_set_object_str() * should_audit(), set_flags_from_config(), make_flags() * _PyAtExit_Call() * init_stdio_encoding() * etc.
